Abstract (en)
[origin: EP1162391A2] Disclosed is a continuously variable transmission (10) in which when a shaft torque is secured by the belt friction force generated by externally pressing a pulley (1). According to the continuously variable transmission, an input operating unit comprising a pressing device (11,54,24) for supplying to the input pulley (1) the elastic force generated by compressing in series an elastic device by a compressing device and a driving source for variably pressing and controlling the input pulley according to a instruction of a controlling device controls the friction force of the input pulley by the variable pressing control for supplying the elastic force, as a consequence of which the shaft torque of the output pulley in the state that a V-belt is in a substantially non-pressing state is indirectly variably controlled via belt tension. <IMAGE>
